Abstract

1337946 Perforating apparatus UNION CARBIDE CORP 19 Oct 1972 [20 Oct 1971] 48113/72 Heading B4B Apparatus for producing apertures in film 10, e.g. of plastics, rubber, paper, metal foil, comprises a support 14 for the film, a piercing member 12, and means 16 for producing relative motion between the support and the piercing member characterized in that the support is retiform having hills and valleys on its surface and the piercing member is pectinate having a plurality of resilient teeth adapted to follow the contours of the support when the member and support are moved relative to each other. The support is in the form of a roller 14 covered with a stainless steel wire screen 26 and rotated by a motor 11, the film being fed by a roll 16 co-operating with the roller 14; a pair of tension rolls 18, 20 are provided. The piercing member 12 is a strip of spring steel having a number of resilient teeth 30 extending from a backbone 32 secured in a holder 34. The ends of the teeth co-operate with the ridges formed by the wire mesh, Fig. 2a, thereby perforating the film. In modifications, the resilient teeth of the piercing member may be formed by a wire brush and the wire screen of the back-up roll replaced by a knurling, embossing or by a perforated metal sheet. Further, the back-up roll may be replaced by a continuous belt.
